8. The Baptism Of Christ
The Baptism of Christ, which was painted by Dutch artist Aert de Gelde in 1710, shows a disc-shaped object shining several beams of light toward the baptismal scene below.
Gelde was a keen student of Rembrandt. Some believe that this would have given the Dutch artist access to the Vatican’s art archives and their “secret knowledge.” As a result, many people believe that Gelde’s paintings, especially this one, are cleverly conveying that secret knowledge to the public.
Whether this is true is open to debate. But four columns of light (rather than a single ray) emanating from the craft seems to suggest that this is an actual object.
The painting now hangs in the Fitzwilliam Museum in Cambridge, UK.
